OPERATION OF VAYOR-CONVERTERS.

Specification of Letters Patent.

Divided and application filed September 1, 1905, Serial No. 276,672. Thisapplication filed October 23, 1907. Serial No. 398,708.

To all whom it may concern Be it known that I, PERCY H. Ti oMAs, a citizen of the United States, and resident of 'Montclair, count-y of Essex, State of New Jersey, have invented certain new and useful Improvements in Operation of Vapor- Converters, of which the following is a specification.

In a certain application, Serial Number 276,672, filed September 1, 1905, of which this application is a division, claims are madeon certain embodiments of the invention here described.

The present application is, in part, a continuation of my prior application Serial Number 140,353, filed January 24th, 1903.

My invention contemplates the application of the principles set forth in the above patent applications to polyphase circuits and provides certain improvements upon the apparatus therein disclosed. For example, the present invention shows the regulator adapted to a polyphase rectifier in such a manner as to provide a specially economical and simple constructionand organization of circuits.

By my invention movable coils may be dispensed with and the regulator core or cores may be relieved of the alternating magnetism found unavoidable in other air rangements. I further provide a means for utilizing a single coil regulator for a three wire two phase circuit thus securing great '91, 92 and as of Fig.2.

In Fig. 1 I show the s stem as applied to a quarter-phase supply, indicated at 74, 74, the terminals of each phase of the source being joined to one pair of the positive electrodes, 75, 75, 75, 75, in a vapor converter,

- 76; and an intermediate point beingconnected through a consumption circuit containing translating devices, 17, 17, 17, being. joined through an inductance, 77, to

, 94, 94, 94, of "the converter 85.

the negative electrode 78 of the said converter.

A switch, 79, may short-circuit the in ductance 77 and a snap or quick-break switch, 80, extendingfrom the lead of the negative electrode to a starting band, 81, surrounding the same may be utilized for creating a critical strain at the negative electrode which will assist in the starting of the apparatus.

A regulator, 82, located in the inducing circuit of the generator, 74, may be utilized for causing constant'alternating current to be supplied to the system.

Fig. 2 shows the system as applied to a three-phase source, the neutral point, 83,

of which is connected to the negative electrode, 84, of a converter, 85, through a work circuit, 16, and an inductance, 86, in the usual way, the work circuit containing Patented Sept. 15, 191.4. Continuation in part of application Serial No. 140,353, filed January 24, 1903.

translating devices, 17 17, 17 such as are lamps. I provide a switch, 87, as usual, for short-circuiting the inductance, 86, if desired. The terminals of the coils, 88, 89 and 90 of the three-phase apparatus are connected through concentric coils, 91, 92 and 93, respectively, to' the positive electrodes, The said concentric coils act upon a common core or armature, 95, located inside the coil 93, and connected with a lever, 96, pivoted at 97, carrying at its opposite end a counterweight, 98. The apparatus including the core, 95, the lever 96, and the counter-weight 98 constitutes a regulator acting in the manner already described.

In Fig. 3 I show a system of circuits generally similar to that illustrated in Fig. 1, although in this instance a two phase primary winding is made to coiiperate with the two phase secondaries, 100, and 101, the terminals of which secondaries are connected, respectively, to the positive electrodes, 102, 102 and 103, 103, inside a vapor converter, 104. Intermediate points of the said secondaries are connected by acircuit 16 through arc lamps or other translating devices, 17 17 17 to the negative electrode, 105, of the converter 104. A regulator consisting of a coil, 106, located in the lead 99, a core, 107, and'suitable counter-balancing devices pivoted at 108, serves to control the supply of both phases to the translating devices, as has already been explained; Fig. 4 shows a plan view of the coils and core of the regulator of Fig. 2 here as before, 91, 92 and 93 represent the three concentric coils and 95 the core.

The various coils and counter-weighted cores in the drawings are shown in diagrammatic form and it is understood that these regulators relate to means and methods whereby a reactance coil acts in opposition to a mechanical force which is so correlated to the magnet pull of the coil that the choking effect of the coil could vary automatically to compensate for changes of resistance in the receiving circuit.
